Title: Tube clarifier in sewage effluent treatment plants - using a settling pipe channel with airlocks
Inventor: HUGHES CHARLES D
IPC: B01D21/00
Filed: 1974-10-11
Abstract: Sewage from a main treatment pond is fec into a settling conduit, the discharge end of which is sealed off by an air lock. A discharge tube is sealed off by a second airlock situated airlock situated between the entrance end of the discharge conduit and the first airlock. Solids are allowed to settle in the conduit, the second airlock released, and clarified effluent withdrawn from the conduit through the discharge tube and replaced with unclarified effluent at a such a rate that the required clarification takes place during the residence time before the effluent reaches the second airlock. Clarified effluent is withdrawn until such time as the settled solids have accumulated to a point where purging is required, after which the second airlock is est. As a tube clarifier in sewage effluent treatment plants. System eliminates all mechanical valving and gating in contact with the effluent, and scoured solids are returned to the treatment pond.

Title: Winding machine bobbin drive - has a friction clutch which blocks the stop unit during winding to prevent slipping
Inventor: ROHNER JOACHIM
IPC: B65H54/42

It can be produced by ion implantation, pref. through a mask over the base zone, the mask having a lateral gradient of its thickness. The mask pref. is an oxide film of thickness decreasing in the direction of the required gradient. For p-channel MOS transistors and n-channel FETs. The occurrence of the 'punch-through' effect is avoided, whilst most of the channel zone has a low dopant concn., so that the characteristic slope, gm = beta (Us + Uth) (in which Uth is the threshold voltage, Ug the gate voltage and beta the slope factor) is not affected.

Title: Spring diving board - made of plastics in enclosed three part sandwich form
Inventor: BOEHM GUENTER
IPC: A63B5/08
Filed: 1975-02-20
Abstract: This plastics diving board is made in a three part sandwich consisting of a corrugated inner core (4) whose ridges run lengthways along the board. They are filled with plastics foam (8). This core (4) is enclosed in an outer shell (2, 3) the upper board of which has soft plastic ribs running across its surface. The outer shells and the core are formed of the same plastics material so that a homogeneous chemical unit is created. Polyester resin has proved to be particularly suitable and can be reinforced by glass fibre or similar. It is advantageous to fill the dales of the corrugation with light material such as wood or foamed plastics.

Title: Adjustable foot scraper for car - is fitted to slide out from under sills and secured by controls through car floor
Inventor: WEBER HUBERT PETER
IPC: B60R3/04
Filed: 1975-05-06
Abstract: The foot scraper (d) comprises an extending metal shaft sliding inside a square section aluminium tube (a) which is secured under the car with securing bolts (b) through the floorpan.

Title: In situ coal gasification cavities - used for waste dump, gas, oil storage or waste heat recovery from carbonaceous ash
Inventor: WENZEL WERNER PROF DR ING
IPC: E21F17/16
Filed: 1975-08-22
Abstract: The cavities are filled from the surface by materials which either remain in them permanently or are temporarily stored and extracted from them later. The former use refers to dumps for nuclear waste, ash, refuse etc. The latter refers to materials which are injected by gaseous or liquid reagents and can undergo physical or chemical reactions in the cavities, or to the storage of gas, oil or water. This eliminates difficulties caused by surface subsidence if large cavities are left unsupported. It also saves any stowing operations with inert filling material introduced from the surface. In many cases, useful byproducts can be obtained (heat by passing air through carbon-containing ashes).

Title: Clutch for motor car - applies clutch force to pressure plate via membrane spring while minimising elastic deformation of plate housing
Inventor: WOERNER GUENTER
IPC: F16D13/58
Filed: 1976-02-10
Abstract: The motor car clutch whose clutch force is transferred to the pressure plate (11) via a membrane spring (13) is designed to reduce the elastic deformation of the membrane spring tongues (16) and the pressure plate housing. The leverage on the membrane spring is the distance (a) of the release from the support position divided by the radial distance (b) from the support position to the point of engagement with the pressure plate. As a consequence of the smaller release force, the release bearing is subjected to a reduced loading which increases the service life of the bearing.

Patent DE-2618508-A1 (DE)
Inventor: DILLIG JULIUS
IPC: H04Q3/42
Filed: 1976-04-27
Abstract: A central automatic dialler (RNG) can be looped into the outgoing connection line (VL) as a separate device. Control codes for the selection of the individual telephone numbers in the automatic dialler (RNG) are therefore always fed in the same form via the connection line from the connector circuit connected upstream, irrespective of the dialling procedure used in the exchange. Existing systems can thus be retrofitted with a central automatic dialler (RNG). <IMAGE>

Title: Mounting of encased electrolytic capacitor - uses centrally penetrating pin whose end away from pin head has breaking line
Inventor: KLASCHKA RUDOLF
IPC: H01G9/00
Filed: 1976-06-11
Abstract: The electrolytic capacitor mounting is used for a metal clad wound capacitor whose one electrode end is connected to a central pin, penetrating the winding, while the other electrode end is coupled to the housing. The latter is tightly closed by an elastic insulating lid abutting the pin head for its insulation against the housing. The pin end away from the head has a break off line whose remote end is pressed into a recess in the housing bottom by application of forces to the pin head. This insertion carries with it also the electrode end to be connected to the housing. As a result the lid is electrically prestressed. The following force relief results in separation of the pin at the break off line from the part pressed into the housing.

Title: Rotary kiln coal gasification - with rapid heating between agglomeration and non-agglomeration temps. to limit agglomerate size
Inventor: CYBRIWSKY ALEXANDER
IPC: C10J3/06
Filed: 1976-09-01
Abstract: In a process for continuous gasification of solid carbonaceous material having a tendency to agglomerate at a pedetermined rate after it attains an agglomerating temperatue and which loses this tendency at a high nonagglomerating temperature, in a kiln having means for selective admission of fluid and at least two zones for devolatilising and gasifying the material, and in which material up to a predetermined agglomerate size can be processed without adversely affecting movement of material through the kiln, carbonaceous material is continuously fed into the kiln and formed into a tumbling zone, sufficient heat is admitted to the bed in the devolatilising zone to raise the material to the agglomerating temperature before the agglomerates have grown larger than the predetermined size, gasification is caused by admitting steam to the bed in the gasifying zone, and rotation of the kiln is continued to cause agglomerated material above the predetermined temperature to be broken up before leaving the kiln. The process enables gasification in a rotary kiln of moderate to strongly caking coal.
